Highlighting HTML Source Code Including Checkbox

I'm looking for a script that will highlight a website's source code with checkboxed per between tags.
It's hard to explain you must see it
Here is a example

http://www.youtubekaydet.com/test.htm

 

$file = file($file);
foreach($file as $f)
{
  echo 'checkbox code here' . highlight_string($f);
}

PHP:

Just one method. You could use the highlight functions at different times in different ways, but this is the gist.

 

I meant different thing. If you check the url that i wrote above.
It groups tags between per them like
for example
<div id="asd"></div>
It groups everything between this tags
